RADIATOR-FILLER-CAP MON OGRAM-LAMP.

Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed December 31, 1915. Serial lilo 69,519.

I citizen of the United States of America, re-

siding at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Radiator-Filler-Cap Monogram-Lamps, of which the following is a specification, reference being had therein to the accompanying drawings.

In the present state of the art in automobile construction it is quite usual to provide the radiator filler cap with monogram plates indicating the make of the car. These plates are conspicuously in view during daylight but at night cannot be seen as they are out of the range of illumination from the lamps.

It is the object of the present invention to provide a monogram cap which is equally discernible in the daylight or at night, and

into this end. the invention comprises the peculiar'construction and combination of cap and lamp as hereinafter set forth.

In the drawings: Figure 1 is a front elevation; Fig. 2 is a section through the cap and lamp; and Fig. 3 is a diagrammatic plan view showing the location of the cap and the manner of connecting the electric circuits thereto.

-A indicates the radiator of an automobile I and B the filler cap therefor which as shown base'f to form the grounded terminal of the hollow base by a set-screwJ. To insulate this socket from the terminal bolt H and also to prevent grounding on the radiator.

cap, the latter is provided with an insulator top on which the hollow base G a plug or contact N secured to a flexible conductor O. The conductor 0 is preferably led to the cap between the outer frame and core of the radiator so as to be concealed with the exception of a small portion passing through an aperture P in the outer frame and extending to the socket M.

The monogram -0r other device exhibited on the lamp may be made in any suitable way to be visible either by reflected or transmitted light. As shown the glass front is formed of two parallelly-arranged glasses E and E, the inner one being preferably a white translucent material and the outer one having a colored surface with the mdnogram or design etched therein. This will renderthe design visible in daylight, while at night'when the lamp is in circuit the design will appear as a transparency.

The construction as described is one which does not in any way interfere with the normal function of the radiator cap, as the latter may be detached when necessary by first disengaging the plug N from the socket M, after which the-cap may be unscrewed.

It is obvious that if desired in place of having one terminal of the lamp grounded a complete insulated circuit may be used.

What I claim as my invention is:

1. The combination with a radiator cap, of an insulator cover therefor, a housing mounted on said cover, an electric lamp within said housing, a terminal for said lamp insulated from said housing and grounded on said'cap, and a terminal connected to said housing.

2. The combination with a radiator, of a cap therefor, an electric lamp mounted on sa1d cap, a conductor for current to said lamp partially extending between the outer frame and core of the radiator, and a flexible extension to said conductor passing out from frame adjacent to saidcap and detachably connected thereto.

3. The combination with a radiator cap, of a housing mounted on said cap, insulating material between said cap and housing,

anelectriclamp within said housing, and electric connections to said lamp permitting of the removal of saidradiatorgcap 4. The; combination with j a; radiator cap, of an insulator-cover therefor, jaghousing mounted on said cover provided with ashollow-base, a lbOltufOI securing; saidhollow base to the cap; insulaitedjqfrom said base and grounded on said cap, an electric lamp 1 withinsaid; housing, and av terminal con nected to seidbase.

In testimony whereof I aflix my signature in presence of twowitnesses,
